Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor is specifically designed for the Lexus LS400, ensuring precise fitment and optimal braking performance. The rotor features a vented design with straight vanes that promote efficient heat dissipation, reducing the risk of brake fade during extended use. The cross-drilled and slotted surface improves pad bite and helps evacuate gases, dust, and water from the braking surface, contributing to consistent stopping power in various driving conditions.

The rotor’s hat is coated to protect against corrosion, extending the service life of the part. The floating disc mounting system allows for slight movement between the rotor and hub, which helps maintain alignment and reduces the chance of warping. With a center hole diameter of 60.1 mm (2.366 inches) and five lug holes sized at 14.5 mm (0.571 inches), this rotor matches the factory specifications for the Lexus LS400.
